Abstract:
An explicit formula expressing the number of classes of primitive hyperbolic elements in the congruence subgroup $\Gamma_0(N)$ (the number of closed geodesics) in terms of the number of equivalence classes of indefinite binary quadratic forms is obtained. The well-known formulae for the numbers of classes of elliptic
and parabolic elements in $\Gamma_0(N)$ are special cases of this formula.
